Topic: Automatic Turret (Read 13233 times)

Dot matrix business card is basically done so next project... automated airsoft turret.Currently I have modifed a cheap AEG to be triggered by a relay, and the relay is triggered by the microcontroller.

AEG was modifed by opening it up, removing unnecessary components, and using gardening shears to cut off excess plastic. A dremel took care of touching it up to look cleaner. The motor is hooked up directly to the relay.

Simple relay board, I decided to make it on protoboard just in case I fried the relay (first time working with them). Some connectors and one diode was all that was needed.

For asthetics, I would be making a laser "eye" like in the portal turrets. A hole is drilled in the center to accomodate a laser. I masked off parts around it that will light up red/green.

Very nice. Which airsoft gun did you start with? I'm assuming you got one that is battery powered so you can activate the trigger with a pulse from the MCU?I have thought of doing this as well, but can not find a cheap enough airsoft pistol around here that is battery powered that I wouldn't mind hacking up.

Razor Concepts used the " Pulse-M70 " fully automatic electronic airsoft gun...(i think...its made by a company called Crosman)

Razor, what's your experience with the reliability of the gun? I've been working on a couple of RC vehicles that originally had airsoft turrets, but the guns got jammed so often, I abandoned them and have switched to IR laser-tag guns. The airsoft guns I used were the cheap ones used in Heng Long tanks. They jammed all the time, and had awful range. I also tried a $20 gun from Walmart, which was also pretty worthless. It had a better range, but jammed a lot also.

I've used the gun unmodified for a long time, it has never jammed, although the original BB feeding system would get stuck so you would have to shake the gun a bit to get the BBs to roll down into the chamber. I added the front-feeding system on this to get rid of that problem.

Use a small vibrating motor, like a pager motor. Have it turn on this motor after every few shots . . . I see this done on feeder systems all the time.

Changed location of ball link to get more pitch throw, and finally came up with an idea for pan. I used a budgetrobotics servo mount on it's side to hold the pan servo. Sorry for poor video quality, I misplaced my camera so I had to use my mp3 player
